I have no idea what ECE_TELEFON is, there also appears to be business and professional versions of the US phone option, is that for the BMW branded phone that goes into the armrest?

It would be interesting to see what activating the TEL_BLUETOOTH option does, can options conflict? like if the ECE_TELEFON is say for the phone in the drawer what will activating the bluetooth option do?

One other thing, when you read the coding you get the hex dump pop up and the line ACe refers to is there 3002, I understand he is using the 4 in 1 lead with dashsoft which looks like a copy/hacked version of carsoft/PA soft v2.1.0?

Obviously NCS expert converts the hex into a readable trace file showing what options are coded etc... isnt it simpler using NCS expert and NCSdummy to change the options rather than changing the hex values directly to see what they do?
